Abstract
We performed an energy consumption analysis of a Wireless Sensor Network (WSN) for precisionagriculture using the OpenThread protocol. Focusing on the Raspberry Pi as a border router, we examine strategiesfor optimizing power usage through peripheral deactivation and CPU frequency adjustments. A custom real-timemonitoring system based on an Arduino board and Hall-effect sensor measures power consumption under varyingnetwork loads. Experimental results show that lower CPU frequencies do not necessarily reduce power draw andthat increased network size raises energy demands. Findings support energy-aware configurations that prioritizesleep scheduling and optimized CPU usage for long-term WSN deployment.
